A high contrast feature provides excellent read- ability in subdued light. Another level indicator is the sight gauge, which is mounted on the oil reser- voir of the engine to provide visual indication of operating fluid lev- els. The gauge is designed to withstand direct flame impinge- ment without fluid loss. Eaton's filler plug has an easy opening quick-disconnect filler cap with strainer to allow operators to add oil into the APU and starter housings. Eaton also provides a full-flow debris monitor which is a special low-pressure drop housing that enhances the capture efficiency of chip detector in the gas turbine engine. Eaton’s Fluid Conveyance provides a variety of Aeroquip® brand hose and fittings assemblies.
